Company exit. Need advice

Hello. I am exiting a management role within Tesla, and by doing so have been given 30 days to exercise my stock options position. I have 169 shares, with a exercise price of 231.28, current stock price hovers around $350. When I preview the sale, I get this breakdown, but don't really understand it. Estimated tax withholding and cost 39,087. Here's the breakdown. Total exercise cost: 39086.32 Estimated tax withholding: 0 Estimated commission: 0 Estimated SEC fees: 1.23 Estimated proceed disbursement fee: 0 \-------- Estimated net proceeds 20,589 Will I owe more tax on this or is the tax included in the 39k? Any advice is appreciated. Hope this is the right place to post. Thank you Edit: They are ISO, as I've seen it asked a few times in replies.
